LED TV Screen


An LED TV screen uses technology that involves light emitting diodes in the video display. These diodes are contained within an LED panel that is actually a component located in the rear of the larger LED display. The LED panels are used in a number of ways as the lighting style is very versatile. These panels can be found in store signs, billboards, and in public transportation vehicles as well. Another use for LED lighting is for stages, and general illumination.

Types of LED Television Screen Options

There are basically two types of panels that create an LED TV screen; Conventional (or discrete LED), and surface mounted devices. The majority of these TV screens are created with discrete LED technology which is sometimes known as individually mounted LED. This technology works by driving together red, green and blue diodes to create a full-color pixel that is generally square. The pixels in an LED panel are placed at equal distances from each other while being measured carefully to create absolute pixel resolution. LED technology is used in various screen sizes. In fact, the largest LED TV screen in the world is located in the Dallas Cowboys stadium, measuring 160 x 72 ft.

Proper Location for an LED Screen

An LED TV screen is compatible both indoors and outdoors. When choosing to use an LED TV outdoors; placement should be determined by lights, electricity, safety, and vehicular access for situations where trucks or cranes are required to move. Furthermore, in large-screen situations, cables for video access and support structures should also be considered. Movement of an LED television screen will require consideration of overhead obstructions. Always account for distance as well as health and safety requirements.

Brief History of the LED Television

In 1977 J.P. Mitchell developed the first LED TV screen. The first model was actually inch thin. This initial prototype received awards and recognition from industry giants such as, General Motors Corp., and NASA. It was first demonstrated at an Expo in Washington DC on May of 1978 by Science Services. The first design included hundreds of LED diodes and TTL memory technology that was created by National Semiconductor who were responsible for designing communication interface products and data solutions. Furthermore, it was well received by local university faculty, as the event was entirely public and attended by foreign representatives as well.

X-Y Scan Technology

The LCD (Liquid Crystal Display), with LED Technology was known early on as a potential TV display alternative. This was a significant accomplishment considering the potential for replacement of the high-voltage analog system that had been used for 70 years, and replacing it with a digital x-y scan system that involves removing color convergence circuits, inductive reflection and electronic beams of the system. It is the digital x-y scan system that helps transform the traditional television into the thinner, more compact versions that we are familiar with today.
